As there is an increase of infections in the male population, concerns have emerged about the potential impact of COVID-19 on male reproductive organs and male fertility. Therefore, this study systematically investigates the current evidence of SARS-CoV-2 impact on male reproduction and pregnancy outcomes, discussing them in light of the evidence published on other coronaviruses. Materials and Methods: Materials and Methods: Literature search was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 24 original articles were included for the analysis, investigating the effects of the infection on semen parameters, male reproductive hormones, and pregnancy outcomes. Further, a Strengths-Weaknesses-Opportunities-Threats (SWOT) analysis was conducted based on the available evidence linking the virus with male reproduction and conception. Results: Results: Although there is limited data, viral mRNA has been identified in semen of infected men, with some evidence of altered seminal parameters. Low testosterone and dihydrotestosterone with raised luteinizing hormone has been reported as well as preterm delivery in pregnant women; however, data regarding vertical transmission remains contradictory and inconclusive. Conclusions: Conclusions: The recent literature provides evidence that male gonads may be potentially vulnerable to SARS-CoV-2 infection, recommending caution to pregnant women and couples planning natural pregnancy or assisted reproduction.

Research paper thumbnail of An Overview on Mesenchymal Stem Cells Derived from Extraembryonic Tissues: Supplement Sources and Isolation Methods

Results: Extra embryonic tissues are the most available source for harvesting of mesenchymal stem cells (MSCs). They make a large number of cells accessible using non-invasive methods of isolation and the least immune-rejection reactions. A successful culture of primary cells requires obtaining a maximum yield of functional and viable cells from the tissues. In addition, there are many reports associated with their differentiation into various kinds of cells, and there are some clinical trials regarding their utilization for patients. Conclusion: Currently, cord blood-MSCs have been tested for cartilage and lung diseases. Umbilical cord-MSCs were tested for liver and neural disorders. However, these MSCs can be isolated, expanded, and cryopreserved in a cell bank for patients in need.

Therefore, an alternative supplement with proper inherent growth-promoting activities is demanded. To find FBS substitute, we tested human umbilical cord blood serum (hUCS) for proliferation of human umbilical cord matrix derived mesenchymal stem cells (hUC-MSCs) and human bone marrow-derived mesenchymal cells (hBM-MSCs). Umbilical cord blood of healthy neonates, delivered by Caesarian section, was collected and the serum was separated. hUC-MSCs and hBM-MSCs were isolated and characterized by assessment of cell surface antigens by flow cytometry, alkaline phosphatase activity and osteogenic/adipogenic differentiation potential. The cells were then cultured in Iscove's Modified Dulbecco's Medium (IMDM) by conventional methods in three preparations: 1- with hUCS, 2- with FBS, and 3- without serum supplement...

Research paper thumbnail of Transplantation of differentiated umbilical cord mesenchymal cells under kidney capsule for control of type I diabetes in rat

Human umbilical cord matrix-derived mesenchymal cells (hUCMC) have successfully been differentiated into insulin producing cells. The isolated hUCM cells were characterized by the expression of stem cell surface markers and by differentiation into adipocytes and osteocytes. The hUCMCs were cultured with different concentrations of neural conditional medium (NCM) and were induced to differentiate into insulin producing cells (IPCs). As 60% NCM concentration resulted in higher nestin and PDX1 expression, the cells were first exposed to 60% NCM and were then induced for IPCs differentiation. PDX1 and insulin gene expression was evaluated in the treated cells. Also, the secretion capacity of the IPCs was assessed by glucose challenge test. IPCs were transferred under the rat kidney capsule. Blood glucose level, weight gain and immunohistochemistry assessments were done in the treated animals. hUCMC expressed mesenchymal cell surface markers and successfully differentiated into adipocytes and osteocytes. Higher NCM concentration resulted in higher PDX1 and nestin expression. The IPCs expressed insulin and PDX1. IPCs were detectable under the kidney capsule 2 months after injection. IPCs transplantation resulted in a sharp decline of blood sugar level and less weight loss. Differentiated hUCM cells could alleviate the insulin deprivation in the rat model of type I diabetes. In addition, higher NCM concentration leads to more differentiation into IPCs and more nestin and PDX1 expression. Kidney capsule can serve as a suitable nominee for IPCs transplantation.

In this study, we evaluated different protocols of insulin secretion to achieve the most appropriate protocol for in vitro insulin secretion. We differentiated human umbilical cord matrix-derived mesenchymal cells (hUCMs) into insulin-producing cell (IPC) by the aim of three previously reported protocols and a modified protocol. The insulin content was analyzed through gene expression and immunocytochemistry (IHC). Dithizone (DTZ) staining was done for identification of islet-like structures. Insulin and C peptide secretion was measured by chemiluminesence immunoassay (CLIA) and enzyme immunoassay (EIA) as well. Reverse transcription-PCR (RT-PCR) showed efficient expression of insulin genes in all the study groups. IHC analysis showed higher expression of insulin and pr...

(Rosaceae) (RD) essential oil and extracts are commonly used as a flavour in herbal medicine which increase libido. Previous studies have shown inhalation of RD flower's oil increases libido and causes protective effects in formaldehyde (FA)-induced testicular damage. The protective effects of aqueous extract of RD on the male reproductive system of mice were examined following FA-induced damage. Forty-eight adult NMRI male mice were randomly assigned to six groups (n = 8): control (normal saline, 10 mg/kg); RD40 (40 mg/kg, p.o.); FA treated (10 mg/kg of 10%, i.p.) and FA + RD treated at 10, 20 and 40 mg/kg (FA + RD10), (FA + RD20) and (FA + RD40), respectively, for 40 days. At the end of treatment regimes, serum testosterone (T) level and the reproductive activity, viz. body/organ weights, testicular structure and sperm characteristics were studied. Formaldehyde administration significantly decreased serum T level (p < 0.001), testicular weight/volume, tubu...
